WHAT IT DOES

What register_student_tool does on Student Registration MCP Server

AI agents use register_student_tool to create or update resources in Student Registration MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Student Registration MCP Server environment.

WHY IT NEEDS A POLICY

Why register_student_tool needs a policy

The tool creates new data records in the student registration system. While this is reversible (records can be deleted), it modifies the system state by adding permanent entries. The presence of validation (required fields, duplicate email prevention) and the potential for an AI to register fake or erroneous students at scale elevates severity to medium.

From the tool's definition Tool description explicitly states it 'Registers a new student' and 'All fields are required. Duplicate emails are not allowed.' This creates new records with validation logic.
